With the upgrade and update of the power regulator, because the trigger of the power regulator is the use of integrated circuit devices, the stability and safety of the power regulator has been improved a lot, and because of its light weight, small size and high efficiency, it is more convenient to maintain, but there are four points in use that need our attention. So what are the four main points? The following Xiaobian will tell you about it, the specific content is as follows:
1, the limitation of the load characteristics of the power regulator used for the resistance load, when the inductive load is at a certain on-angle, it may cause the thyristor to not be on-.
2, the influence of the power factor of the power regulator may lead to a decrease in the power factor, especially in the case of "depth control", the power factor will be lower, such as the regulator needs to be used for a long time or more for depth control, appropriate compensation measures should be taken.
What are the use points of power regulator
3, define the regulation range of the power supply voltage regulator, the output voltage of the thyristor power regulator 0-380V (380V input voltage, the problem of conduction, because the actual output voltage will be greater than 380V slightly lower), such as claims greater than 380V, you should consider using the induction regulator (which can be designed to output voltage 0-2X380V).
4, the thyristor has many advantages in overvoltage and overcurrent protection, but the ability to withstand overvoltage and overcurrent is poor, short-term overvoltage and overcurrent will lead to component damage. Although there is a certain safety factor in the selection of thyristors, some protective measures still need to be taken. Overcurrent protection generally adopts automatic air switches and fast fuses, and overcurrent protection adopts resistance and capacitance absorption devices and varistors. The power supply should be cut off when not in use.
